St. Louis, MO – Winter makes its presence known across the Gateway City today as gray skies thicken and snow begins falling by late afternoon, coating roads and rooftops in a fresh white dusting. The scene feels deceptively calm — light flakes drifting across the Mississippi — but forecasters warn that even 1–2 inches of accumulation could bring slippery travel conditions through the evening commute.
According to the National Weather Service in St. Louis, snow will increase after 5 p.m., tapering by early Tuesday morning. Roads along I-70, I-44, and I-55 may become slick as temperatures hover in the mid-20s to near 30°F, allowing ice to form quickly on untreated surfaces. Visibility could briefly drop during heavier bursts.
Tuesday brings clearing skies and calmer winds, but the cold remains sharp — morning lows near 22°F, highs barely reaching 31°F. Midweek looks brighter, with mostly sunny conditions Wednesday and highs around 40°F. Another chance of light snow returns late Thursday into Friday, part of a broader early-December pattern delivering on-and-off wintry waves across the Midwest.
Residents should allow extra travel time tonight, especially across bridges and elevated surfaces prone to early icing. Keep windshield wipers up, headlights on, and avoid sudden stops.
